Description

Technical Field

[0001] This utility model relates to the field of circuit board processing, and in particular to a drilling device for conveniently fixing PCB boards. Background Technology

[0002] When drilling circuit boards, to obtain high-quality holes and protect the equipment, a backing plate is typically placed under the circuit board to be processed, and a cover plate is placed on top of it. The main function of the backing plate is to support the drill bit as it penetrates the circuit board, preventing it from directly contacting and damaging the worktable or related equipment below. It also effectively reduces burrs at the drill exit point, improving the smoothness and positioning accuracy of the hole wall. The cover plate fits tightly against the circuit board surface, fixing its position and suppressing vibration or displacement that may be caused by the high-speed rotation of the drill bit and feed pressure during drilling. It also reduces burrs at the drill entry point, further ensuring processing accuracy.

[0003] Currently, the conventional method for assembling and securing the circuit board, pad, and cover plate is to manually bind them together with tape along their edges. This method has significant drawbacks: First, the process is cumbersome and time-consuming, requiring workers to carefully align and apply multiple strips of tape before processing each circuit board, resulting in low efficiency and high manpower consumption; second, this disposable tape is torn off and discarded after drilling, cannot be reused, and leads to a continuous waste of material resources over time.

[0024] Example: This example provides a drilling device for conveniently fixing a PCB board. See [link to example]. Figure 1-5 Specifically, it includes a drilling machine body 1 and a drilling machine table 11 for placing the processing plate 200. The processing area on the upper surface of the drilling machine table 11 is rotatably provided with a first positioning frame 12 and a second positioning frame 13. The second positioning frame 13 is located on the upper surface of the first positioning frame 12 and forms a stacked rotating structure with the first positioning frame 12. The second positioning frame 13 is provided with a fixing component 2, which is configured to press and fix the stacked pad 100, processing plate 200 and cover plate 300 together.

[0025] In this embodiment, the drilling machine body 1 is a mechanical drilling machine. The size and thickness of the inner wall of the first positioning frame 12 are adapted to the size of the pad 100. The second positioning frame 13 has the same area as the first positioning frame 12 and is attached to the surface of the first positioning frame 12. During operation, the first positioning frame 12 is first rotated to fit against the drilling machine table 11. Then, the pad 100 is placed inside the first positioning frame 12 and positioned in the processing area. Next, the processing plate 200 is attached to the pad 100, and then the cover plate 300 is attached to the processing plate 200. Finally, the second positioning frame 13 is rotated to fit against the first positioning frame 12. The fixing component 2 is used to position the processing plate 200 and the cover plate 300 at the center of the pad 100 and to position the processing plate 200 and the cover plate 300 on the pad 100, reducing the difficulty of operation and improving the drilling efficiency.

[0026] In the specific implementation process, such as Figure 3 and Figure 5 As shown, the fixing component 2 includes two drive rods 21 and a drive member that are slidably mounted on the second positioning frame 13. One end of each drive rod 21 is fixed with an L-shaped fixing strip 22. The inner side of the fixing strip 22 is in contact with the end face of the processing plate 200 and the cover plate 300. The other end of each drive rod 21 is connected to the drive member.

[0027] In this embodiment, the driving component synchronously drives the two driving rods 21 to move in opposite directions. The driving rods 21 drive the fixing strip 22 to fit against the end faces of the processing plate 200 and the cover plate 300. The fixing strip 22 is L-shaped and partially presses against the surface of the cover plate 300, thereby fixing the bottom processing plate 200 and the cover plate 300 in two directions, making the fixing between the processing plate 200, the cover plate 300 and the pad 100 more secure.

[0028] In the specific implementation process, such as Figure 3 and Figure 5 As shown, the driving component includes two fixed blocks 3 fixedly installed on the upper surface of the first positioning frame 12. A bidirectional screw 31 is rotatably provided between the fixed blocks 3. Both ends of the bidirectional screw 31 are located inside the fixed blocks 3. One end of the driving rod 21 is slidably disposed inside the fixed block 3. The end of the driving rod 21 is threadedly connected to the bidirectional screw 31. A rotating ring 32 is fixedly provided at one end of the bidirectional screw 31.

[0029] In this embodiment, the rotating ring 32 is an internal hexagonal ring. The rotating ring 32 is driven to rotate by a hexagonal tool. The rotating ring 32 drives the bidirectional screw 31 to rotate. The threads at both ends of the bidirectional screw 31 are opposite, thereby driving the two drive rods 21 to move in opposite directions, realizing the opening and fixing functions.

[0030] In the specific implementation process, such as Figure 3 and Figure 4 As shown, two limiting plates 4 are symmetrically provided on the inner side of the second positioning frame 13, and a slope 41 is provided on one side of the limiting plate 4.

[0031] In this embodiment, after the second positioning frame 13 rotates and fits against the first positioning frame 12, the inclined surface 41 of the limiting plate 4 will contact both ends of the cover plate 300 and the processing plate 200. The limiting plate 4 will push the cover plate 300 and the processing plate 200 towards the middle of the pad 100. The position of the cover plate 300 and the processing plate 200 will be adjusted first, and then the position of the cover plate 300 and the processing plate 200 will be fixed by the fixing component 2.

[0032] In the specific implementation process, such as Figure 2 and Figure 3 As shown, a fixing plate 5 is fixedly provided on one side of the outer wall of the first positioning frame 12 and the second positioning frame 13. A movable ring 51 is rotatably provided on the fixing plate 5, and a bolt 52 is inserted into the fixing plate 5.

[0033] In this embodiment, bolts 52 are used to connect the first positioning frame 12 and the second positioning frame 13 to the drilling machine table 11 through two fixing plates 5, thereby fixing the positions of the first positioning frame 12 and the second positioning frame 13. By rotating the movable ring 51, it is convenient for the staff to hold and exert force to make the first positioning frame 12 and the second positioning frame 13 rotate, which facilitates unloading.

[0034] In the specific implementation process, such as Figure 2 and Figure 3 As shown, a fixed frame 6 is fixedly installed in the processing area of ​​the drilling machine table 11. Two connecting plates 61 are arranged side by side and rotated inside the fixed frame 6. The two connecting plates 61 are fixedly connected to the outer walls of the first positioning frame 12 and the second positioning frame 13, respectively.

[0035] In this embodiment, the first positioning frame 12 and the second positioning frame 13 are rotatably connected to the shaft at the end of the connecting plate 61 and the fixing frame 6, so that the first positioning frame 12 and the second positioning frame 13 can rotate.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
